New Zealand captain Brendon McCullum has full faith in the International Cricket Council’s fight against fixing despite the leak of his confidential testimony.

McCullum held a short press conference in Christchurch on Thursday, restating that he has never been involved in fixing and expressed no regrets about giving his evidence to investigators.

That testimony, in which he describes being approached by “player X” in 2008 to fix games, was leaked to British media.

He says he was shocked to read about it in the media last week but thanked ICC chief executive Dave Richardson for a personal apology two days ago and for publicly commending his actions.

McCullum says it is crucial that cricket remains vigilant in the fight against corruption and not be put off by the leaks of his testimony, along with that of former New Zealand teammate Lou Vincent, who has admitted involvement in fixing.

“If one of my players finds themselves in the same situation, I’d encourage them to go down the same route that I’ve taken,” he said.

“Obviously there’s a couple of circumstances which have slightly tainted the game but the majority of the people in the sport uphold the traditions and the respect for the sport which everyone loves.”

He offered no comment when asked for the identity of player X.

McCullum says he expects to be questioned again by the ICC anti-corruption unit and said there was still “a long road ahead” in the worldwide investigation.

The 32-year-old has taken a break from his Indian Premier League commitments this week to be present at the birth of his third child in Christchurch.

Meanwhile, the ICC has served an injunction against a British newspaper the Daily Mail in a bid to prevent further leaks into its anti-corruption investigation reaching the public.
